This invention relates to a safety signal, the general object of the invention being to provide an oscillating arm carrying a lamp casing and a bell provided with a hammer, a wheel for operating the arm and hammer and means for rotating the wheel.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Fig. 1 is an elevation of the invention.

Fig. 2 is an edge View thereof.

In these drawings, the numeral indicates a platform, adjacent one end of which is supported a post 2 carrying a bell 3 at its upper end, said bell being horizontally arranged as shown.

A second upright l is supported at said end ofthe platform and has one end of an arm 5 pivoted to its upper end, said arm being formed of two sections having their adjacent ends threaded toreceive a sleeve 6 so that the arm is adjustable as to its length. A lamp housing I is connected to the lower end of the arm and contains the usual lamp and reflector. An upright 8 is supported by the intermediate part of the platform'and supports at its upper end a horizontal cylinder 9 containing a spring l0 which projects from the rear end of the cylinder, the spring being adjustable by a set screw l which is threaded into the front end of the cylinder. A hammer I2 is pivoted to a part of this upright 8 and has its head I3 adapted to strike the bell, the hammer being thrown towards the bell to strike the same by a spring M which connects an intermediate part of the hammer to a part of the upright 8. The spring H] is arranged in the path of movement of the hammer and acts as a bumper for the hammer. A shaft I5 is rotatably supported on the platform and has a wheel or disk l6 fastened thereto, the wheel carrying a plurality of radially arranged pins or projections ll which Will engage a pivoted dog it on the lower end of the hammer during the rotation of the wheel so that the hammer moves rearwardly against the action of the spring M at intervals and then when a pin or projection ll passes the dog, the spring M will cause the hammer to strike the bell to sound the same. A spring l9 connects the dog to a part of the hammer, the dog being preferably of the shape shown in Fig. 1 with a rear straight end for engagement by the pin.

60 This arrangement of dog will permit the dog to is pivoted to the arm 5 so that during rotation 5 of thewheel, the arm and the lamp housing 1 will be oscillated, a spring 2| connecting the arm with a part of the platform, acting to move the arm towards the wheel.

A motor M is supported by the platform and 10 has a pinion 22 on its shaft meshing with a gear 23 on a shaft 24 which is rotatably supported from the platform and this shaft 24 carries a pinion 25 which meshes with a gear 26 attached to the shaft l5 which carries the wheel 15 I6. Thus, when the motor is in operation, the wheel I6 is rotated from the chain of gearing as will be understood. The spring 2| will pull back the arm 5 into inoperative position when the apparatus is idle and if this movement of the parts 20 by the spring 2| rotates the wheel H5 in a reverse direction, the pins will simply rock the dog l8 as they pass the same. Thus, when the wheel I6 is moved in a reverse direction by the movement of the arm 5 by the spring 2|, or for 25 any reason there is no danger of damaging the parts.

This device will give a visual and audible signal and may be used as a traffic warning wherever desired and is particularly designed for bridge 30 or railroad warnings.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be 35 made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

I claim: 40

1. A device of the class described comprising a platform, an upright carried thereby, a bell supported at the upper end of the upright, a second upright on the platform, a hammer pivotally supported thereby, a spring for moving the ham- 45 mer against the. bell, a bumper for the hammer,

a spring-actuated dog at the lower end of the hammer, a wheel rotatably supported by the platform and having projections for engaging the dog for operating the hammer, and means for 5 rotating the wheel.

2. In a signal device of the class described, comprising a swinging signal arm, a bell and a hammer for striking the bell; a rotary wheel, means for swinging the arm bythe rotary movement of the wheel, projections carried by the wheel and actuating the hammer to cause said hammer to strike the bell, and means for rotating the wheel.
